[MAIPC] Non-chemical Viburnum control

[Marc Imlay]

Agreed! In Montgomery County thousands of citizens are getting Lyme disease from deer ticks because patches of  Asiatic Bush Honeysuckle increases the risk by a factor of ten. Cut stump is needed with herbicide to effectively remove it. Marc Imlay

I encourage people to think of herbicides, when used in highly targeted and minimalist treatments like stump treatments, as a form of western medicine for nature. We don't deprive doctors and ourselves of the use of manufactured medicines, all of which have some level of toxicity. Why, then, are we depriving land managers of similar options for the healing of nature? It's unfair to us, and yet another example of how people adopt attitudes that fill their need to feel good about themselves, rather than figuring out what's best for nature. 

 

The NY Times feeds this sort of thinking with articles like this one <https://www.nytimes.com/2019/10/17/dining/drinks/climate-change-regenerative-agriculture-wine.html#commentsContainer&permid=103173259:103173259> , a couple days ago, which leads with a wine grower denying the reality of invasive species. NY Times columnist Margaret Renkl has also characterized all pesticides as poisons. Oftentimes, these blanket condemnations come from the same people who claim all plants are good. It's lazy thinking, usually by people who don't actually have to do the work, and represents a failure to make important distinctions. Few people would take seriously the contention that all bacteria are good, and that we shouldn't use antibiotics because they are overused in agriculture. What's actually being said is that people matter, and nature really doesn't. And land managers are left holding the bag.

That's good to know.  There must be ways that are still avoiding pesticides, but less obtrusive and easier to manage than tarps.  Maybe something thick and environmentally safe painted on (if allowed by herbicide regulations), or string/stakes and a biodegradable plastic.

It resprouts well from the stump when cut and it does, in general, resprout some from roots. My observations though suggest that no new root sprouts emerged from tarped or cut plants.

Without a tarp, would this plant typically resprout from the stump or in a bushy manner with shoots at some distance away, and if so, up to how far away?

All

 

Over the last couple of years I have been volunteering for Montgomery County, MD as a Weed Warrior. As part of that work I have been faced with a stand of Viburnum and I have been restricted from using chemicals. I tested a few treatments and learned that tarping is very effective and gained some other insights. It isn't really a robust study but the results are nonetheless conclusive and directly pertinent to land managers. I'm attaching it here in the hopes that others managing woody plants in the mid Atlantic will consider tarping when chemical control is not an option.
